Description

P/00/011 Regulation 3.2 AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Invention Title: Benzotriazine inhibitors of kinases The following statement is a full description of this invention, including the best method of performing it known to us: IA BENZOTRIAZINE INHIBITORS OF KINASES CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of priority under 35 U.S.C. § 119(e) of patent applications U.S. Serial Number 60/561,237 filed April 8, 2004, and 60/643,439 filed January 12, 2005, the entire content of which is incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention relates generally to the use of compounds to treat a variety of disorders, diseases and pathologic conditions and more specifically to the use of benzotriazine compounds to treat disorders. BACKGROUND [0003] c-Src plays a major role in the growth, progression and metastasis of a large number of cancers. c-Src can be the transforming element of the oncogenic Rous sarcoma retrovirus. Subsequently, it has been demonstrated that c-Src kinase can have the oncogenic potential. Gene knockout experiments suggest that inhibition of some members of the Src family might have potential therapeutic benefit. [0004] Tyrosine kinases (TKs) phosphorylate tyrosine residues in peptides and proteins. These enzymes are key elements in the regulation of cell signaling including cell proliferation and cell differentiation. Protein TKs comprise the receptor TKs, including the epidermal growth family members (HER1 and HER2 for example), platelet derived growth factor (PDGF) and kinases that play a role in angiogenesis (Tie-2 and KDR for example), and the cellular or non-receptor kinases, which include members of the Src family.

2 [00051 c-Src TK is one of three members of the Src family expressed ubiquitously. c-Src is expressed at low levels in most cell types and, in the absence of the appropriate extracellular stimuli, maintained in an inactive conformation through phosphorylation of a regulatory tyrosine domain at Tyr530. Activation of c-Src occurs through dephosphorylation of the Tyr530 site and phosphorylation of a second tyrosine, Tyr419, present in the kinase domain of the enzyme. 100061 Src kinase modulates signal transduction through multiple oncogenic pathways, including EGFR, HER2, PDGFR, FGFR and VEGFR. Thus, blocking signaling through the inhibition of the kinase activity of Src can be an effective means of modulating aberrant pathways that drive the oncogenic transformation of cells. [0007] There exists a body of evidence of misregulated increased kinase activity of c Src in several human tumor types, most notably colon and breast tumors. Misregulated c Src TK activity has also been associated with adhesion and cytoskeletal changes both in tumor cells and otherwise, ultimately resulting in an invasive phenotype that may be motile. c-Src TK activity has been shown to be an important component in the epithelial to mesenchymal transition that occurs in the early stages of invasion of carcinoma cells. c-Src activity is also known to be essential in the turnover of local adhesions, a critical cell-motility component. In in vivo models of metastases, c-Src inhibition markedly reduces the rate of lymph and liver metastases. Clinical data supports the link between misregulated Src activity and the increased invasive potential of tumor cells. In colon tumors, increased c-Src TK activity has been shown to correlate to tumor progression, with the highest activity found in metastatic tissue. Increased Src activity in colon tumors might be an indicator of poor prognosis. In breast and ovarian cancers, enhancement of Src kinase activity has been reported, and in transitional cell carcinoma of the bladder, c-Src activity peaked as superficial tumors became muscle invasive. [0008] Biochemically, cellular stimuli that lead to Src activation result in increased association between Src and the cytoskeleton. As a result, Src mediates the phosphorylation of many intracellular substrates such as EGFR, FAK, PYK2, paxillin, 3 Stat3, and cyclin D. The biological effects of these interactions affect cell motility, adhesion, cell cycle progression, and apoptosis and might have some connection to the disease related effects stated above. Thus, Src plays a role in responses to regional hypoxia, limited nutrients, and internal cellular effects to self-destruct. [0009] Increased c-Src TK activity results in breakdown of the E-cadherin-mediated epithelial cell-cell adhesion, which can be restored by Src inhibition. Intimate connections between increased VEGF activity, Src activity, and cellular barrier function related to vascular leak have been also demonstrated. Inhibition of Src results in decrease in vascular leak when exogenous VEGF is administered in in vivo studies. Examples where excessive vascular permeability leads to particularly deleterious effects include pulmonary edema, cerebral edema, and cardiac edema. [00101 The cascade of events leading to loss of endothelial barrier function is complex and incompletely understood. Data support some role for kinases in this process. For example, VEGF-mediated edema has been shown to involve intracellular signaling by Src family kinases, protein kinase C, and Akt kinase. Rho-associated kinases have been linked to thrombin-mediated vascular leakage, and protein kinase C to TNF-induced leakage. Kinases are believed to mediate the phosphorylation of junctional proteins such as beta-catenin and vascular endothelial VE-cadherin, leading to the dissolution of adherens junctions and the dissociation of cadherin-catenin complexes from their cytoskeletal anchors. Proteins which regulate the intercellular contractile machinery such as myosin light chain kinase (MLCK) and myosin light chain (MLC) are also activated, resulting in cellular contraction, and therefore an opening of intercellular junctions. [00111 A general approach to the inhibition of vascular leakage can be to interfere with any of the underlying mechanistic pathways, whether by inhibition of kinase signaling or the intercellular contractile apparatus or other cellular processes. This can then lead to potential treatments for edema and its associated pathologies. For example, inhibiting edema formation should be beneficial to overall patient outcome in situations such as inflammation, allergic diseases, cancer, cerebral stroke, myocardial infarction, pulmonary and cardiac insufficiency, renal failure, and retinopathies, to name a few. Furthermore, as edema is a general consequence of tissue hypoxia, it can also be concluded that inhibition of vascular leakage represents a potential approach to the treatment of tissue hypoxia. For example, interruption of blood flow by pathologic conditions (such as thrombus formation) or medical intervention (such as cardioplegia, organ transplantation, and angioplasty) could be treated both acutely and prophylactically using inhibitors of vascular leakage, especially as in the case of Src inhibitors. [0012] Accordingly, a small molecule inhibitor of c-Src can be beneficial for the treatment of several disease states. SUMMARY [00131 The present invention provides methods of use for certain chemical compounds such as kinase inhibitors for treatment of various diseases, disorders, and pathologies, for example, cancer, and vascular disorders, such as myocardial infarction (Ml), stroke, or ischemia. [00141 The benzotriazine compounds described in this invention may block the enzymatic activity of some or many of the members of the Src family, in addition to blocking the activity of other receptor and non-receptor kinases. Such compounds may be beneficial for treatment of the diseases where disorders affect cell motility, adhesion, and cell cycle progression, and in addition, diseases with related hypoxic conditions, osteoporosis and conditions, which result from or are related to increases in vascular permeability, inflammation or respiratory distress, tumor growth, invasion, angiogenesis, metastases and apoptosis. 10015] According to the embodiments of the invention, some examples of kinase inhibitors that can be used to bring about beneficial therapeutic results include inhibitors of Src kinase.

[0072] Src-family tyrosine kinases other than Lck, such as Hck and Fgr, are important in the Fc gamma receptor induced respiratory burst of neutrophils as well as the Fc gamma receptor responses of monocytes and macrophages. The compositions and methods of the present invention may be useful in inhibiting the Fc gamma induced respiratory burst response in neutrophils, and may also be useful in inhibiting the Fc gamma dependent production of TNF alpha. The ability to inhibit Fe gamma receptor dependent neutrophil, monocyte and macrophage responses would result in additional anti-inflammatory activity for the compounds employed in invention methods. This activity would be especially of value, for example, in the treatment of inflammatory diseases, such as arthritis or inflammatory bowel disease. The compositions and methods of the present invention may also be useful in the treatment of autoimmune glomerulonephritis and other instances of glomerulonephritis induced by deposition of 56 immune complexes in the kidney that trigger Fe gamma receptor responses and which can lead to kidney damage. [0073] In addition, certain Src-family tyrosine kinases, such as Lyn and Src, may be important in the Fc epsilon receptor induced degranulation of mast cells and basophils that plays an important role in asthma, allergic rhinitis, and other allergic disease. Fc epsilon receptors are stimulated by IgE-antigen complexes. Compounds employed in the methods of the present invention may inhibit the Fe epsilon induced degranulation responses. The ability to inhibit Fc epsilon receptor dependent mast cell and basophil responses may result in additional anti-inflammatory activity for the present compounds beyond their effect on T.cells. [0074] The present invention also provides articles of manufacture comprising packaging material and a pharmaceutical composition contained within the packaging material, wherein the packaging material comprises a label which indicates that the pharmaceutical composition can be used for treatment of disorders and wherein the pharmaceutical composition comprises a compound according to the present invention. Thus, in one aspect, the invention provides a pharmaceutical composition including a therapeutic agent and a compound of the invention, wherein the compound is present in a concentration effective to reduce vascular leakage associated with indications or therapeutic agents which have vascular leak as a side effect. For example, administration of a compound of the invention can be in conjunction with IL-2, immunotoxins, antibodies or chemotherapeutics. In these cases, IL-2, immunotoxin, antibody or chemotherapeutic concentration can be determined by one having ordinary skill in the art according to standard treatment regimen or, for example, as determined by an in vivo animal assay. [00751 The present invention also provides pharmaceutical compositions comprising IL-2, immunotoxin, antibody or chemotherapeutic and at least one invention compound in an amount effective for inhibiting vascular permeability, and a pharmaceutically acceptable vehicle or diluent. The compositions of the present invention may contain 57 other therapeutic agents, and may be formulated, for example, by employing conventional solid or liquid vehicles or diluents, as well as pharmaceutical additives of a type appropriate to the mode of desired administration (for example, excipients, binders, preservatives, stabilizers, flavors, etc.) according to techniques known in the art of pharmaceutical formulation. [00761 The compounds of the invention may be formulated into therapeutic compositions as natural or salt forms. Pharmaceutically acceptable non-toxic salts include the base addition salts (formed with free carboxyl or other anionic groups) which may be derived from inorganic bases such as, for example, sodium, potassium, ammonium, calcium, or ferric hydroxides, and such organic bases as isopropylamine, trimethylamine, 2-ethylamino-ethanol, histidine, procaine, and the like. Such salts may also be formed as acid addition salts with any free cationic groups and will generally be formed with inorganic acids such as, for example, hydrochloric, sulfuric, or phosphoric acids, or organic acids such as acetic, citric, p-toluenesulfonic, methanesulfonic acid, oxalic, tartaric, mandelic, and the like. Salts of the invention include amine salts formed by the protonation of an amino group with inorganic acids such as hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, phosphoric acid, and the like. Salts of the invention also include amine salts formed by the protonation of an amino group with suitable organic acids, such as p-toluenesulfonic acid, acetic acid, and the like. Additional excipients which are contemplated for use in the practice of the present invention are those available to those of ordinary skill in the art, for example, those found in the United States Pharmacopeia Vol. XXIII and National Formulary Vol. XVII, U.S. Pharmacopeia Convention, Inc., Rockville, MD (1989), the relevant contents of which is incorporated herein by reference. In addition, polymorphs of the invention compounds are included in the present invention. [0077] Pharmaceutical compositions of the invention may be administered by any suitable means, for example, orally, such as in the form of tablets, capsules, granules or powders; sublingually; buccally; parenterally, such as by subcutaneous, intravenous, intramuscular, intrathecal, or intracistemal injection or infusion techniques (e.g., as sterile 58 injectable aqueous or non-aqueous solutions or suspensions); nasally such as by inhalation spray; topically, such as in the form of a cream or ointment; or rectally such as in the form of suppositories; in dosage unit formulations containing non-toxic, pharmaceutically acceptable vehicles or diluents. The present compounds may, for example, be administered in a form suitable for immediate release or extended release. Immediate release or extended release may be achieved by the use of suitable pharmaceutical compositions comprising the present compounds, or, particularly in the case of extended release, by the use of devices such as subcutaneous implants or osmotic pumps. The present compounds may also be administered liposomally. [0078] In addition to primates, such as humans, a variety of other mammals can be treated according to the method of the present invention. For instance, mammals including, but not limited to, cows, sheep, goats, horses, dogs, cats, guinea pigs, rats or other bovine, ovine, equine, canine, feline, rodent or murine species can be treated. However, the method can also be practiced in other species, such as avian species (e.g., chickens). [0079] The pharmaceutical compositions for the administration of the compounds of this embodiment either alone or in combination with IL-2, immunotoxin, antibody or chemotherapeutic may conveniently be presented in dosage unit form and may be prepared by any of the methods well known in the art of pharmacy. All methods include the step of bringing the active ingredient into association with the carrier which constitutes one or more accessory ingredients. In general, the pharmaceutical compositions are prepared by uniformly and intimately bringing the active ingredient into association with a liquid carrier or a finely divided solid carrier or both, and then, if necessary, shaping the product into the desired formulation. In the pharmaceutical composition the active object compound is included in an amount sufficient to produce the desired effect upon the process or condition of diseases. The pharmaceutical compositions containing the active ingredient may be in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixirs.

59 [0080] Compositions intended for oral use may be prepared according to any method known to the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents and preserving agents in order to provide pharmaceutically elegant and palatable preparations. Tablets contain the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients which are suitable for the manufacture of tablets. These excipients may be for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example, corn starch, or alginic acid; binding agents, for example starch, gelatin or acacia, and lubricating agents, for example magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate may be employed. They may also be coated to form osmotic therapeutic tablets for control release. [00811 Formulations for oral use may also be presented as hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, for example peanut oil, liquid paraffin, or olive oil. [0082] Aqueous suspensions contain the active materials in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients are suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydroxy propylmethylcellulose, sodium alginate, polyvinyl-pyrrolidoie, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally-occurring phosphatide, for example lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long chain aliphatic alcohols, for example heptadecaethyleneoxycetanol, or condensation 60 products of ethylene oxide with partial esters derived from fatty acids and a hexitol such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. Also useful as a solubilizer is polyethylene glycol, for example. The aqueous suspensions may also contain one or more preservatives, for example ethyl, or n propyl, p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose or saccharin. [0083] Oily suspensions may be formulated by suspending the active ingredient in a vegetable oil, for example arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin. The oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol. Sweetening agents such as those set forth above, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an anti-oxidant such as ascorbic acid. [00841 Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients, for example sweetening, flavoring and coloring agents, may also be present. [0085] Syrups and elixirs may be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative and flavoring and coloring agents. [0086] The pharmaceutical compositions may be in the form of a sterile injectable aqueous or oleagenous suspension. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents which have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a parenterally-acceptable diluent or solvent or 61 cosolvent or complexing agent or dispersing agent or excipient or combination thereof, for example 1,3-butanediol, polyethylene glycols, polypropylene glycols, ethanol or other alcohols, povidones, various brands of TWEEN surfactant, sodium dodecyl sulfate, sodium deoxycholate, dimethylacetamide, polysorbates, poloxamers, cyclodextrins, lipids, and recipients such as inorganic salts (e.g., sodium chloride), buffering agents (e.g., sodium citrate, sodium phosphate), and sugars (e.g., saccharose and dextrose). Among the acceptable vehicles and solvents that may be employed are water, dextrose solutions, Ringer's solutions and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables. [00871 Depending on the condition being treated, these pharmaceutical compositions may be formulated and administered systemically or locally. Techniques for formulation and administration may be found in the latest edition of "Remington's Pharmaceutical Sciences" (Mack Publishing Co, Easton Pa.). Suitable routes may, for example, include oral or transmucosal administration; as well as parenteral delivery, including intramuscular, subcutaneous, intramedullary, intrathecal, intraventricular, intravenous, intraperitoneal, or intranasal administration. For injection, the pharmaceutical compositions of the invention may be formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hanks' solution, Ringer's solution, or physiologically buffered saline. For tissue or cellular administration, penetrants appropriate to the particular barrier to be permeated are used in the formulation. Such penetrants are generally known in the art. Pharmaceutical formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form. Additionally, suspensions of the active compounds may be prepared as appropriate oily injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances that increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran.

62 Optionally, the suspension may also contain suitable stabilizers or agents that increase the solubility of the compounds to allow. for the preparation of highly concentrated solutions. [0088] The compounds of the present invention may also be administered in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials are cocoa butter and polyethylene glycols. [0089] For topical use, creams, ointments, jellies, solutions or suspensions, etc., containing the compounds of the present invention are employed. (For purposes of this application, topical application shall include mouthwashes and gargles). [0090] In one aspect, the invention compounds are administered in combination with an anti-inflammatory agent, antihistamines, chemotherapeutic agent, immunomodulator, therapeutic antibody or a protein kinase inhibitor, e.g., a tyrosine kinase inhibitor, to a subject in need of such treatment.

[0094] When other therapeutic agents are employed in combination with the compounds of the present invention they may be used for example in amounts as noted in the Physician Desk Reference (PDR) or as otherwise determined by one having ordinary skill in the art. [0095] In the treatment or prevention of conditions which involve compromised vasculostasis an appropriate dosage level can generally be between about 0.01 and about 500 mg per 1 kg of patient body weight per day which can be administered in single or multiple doses. For example, the dosage level can be between about 0.01 and about 250 mg/kg per day; more narrowly, between about 0.5 and about 100 mg/kg per day. A suitable dosage level can be between about 0.01 and about 250 mg/kg per day, between about 0.05 and about 100 mg/kg per day, or between about 0.1 and about 50 mg/kg per day, or about 1.0 mg/kg per day. For example, within this range the dosage can be between about 0.05 and about 0.5 mg/kg per day, or between about 0.5 and about 5 mg/kg per day, or between about 5 and about 50 mg/kg per day. For oral administration, the compositions can be provided in the form of tablets containing between about 1.0 and about 1,000 mg of the active ingredient, for example, about 1.0, about 5.0, about 10.0, about 15.0, about'20.0, about 25.0, about 50.0, about 75.0, about 100.0, about 150.0, about 200.0, about 250.0, about 300.0, about 400.0, about 500.0, about 600.0, about 750.0, about 800.0, about 900.0, and about 1,000.0 mg of the active ingredient for the symptomatic adjustment of the dosage to the patient to be treated. The compounds can be administered on a regimen of 1 to 4 times per day, such as once or twice per day. There may be a period of no administration followed by another regimen of administration. Preferably, administration of the compound is closely associated with the schedule of IL- 66 2 administration. For example, administration can be prior to, simultaneously with or immediately following IL-2 administration. [0096] It will be understood, however, that the specific dose level and frequency of dosage for any particular patient may be varied and will depend upon a variety of factors including the activity of the specific compound employed, the metabolic stability and length of action of that compound, the age, body weight, general health, sex, diet, mode and time of administration, rate of excretion, drug combination, the severity of the particular condition, and the host undergoing therapy. [0097] Compounds of the present invention can be used, alone or in combination with an effective amount of a therapeutic antibody (or therapeutic fragment thereof), a chemotherapeutic or an immunotoxic agent, for treatment of tumors. While doxorubicin, docetaxel, or taxol are described in the present application as illustrative examples of chemotherapeutic agents, it should be understood that the invention includes combination therapy including a compound of the invention, including but not limited to vasculostatic agents, such as tyrosine, serine or threonine kinase inhibitors, for example, Src-family inhibitors, and any chemotherapeutic agent or therapeutic antibody.

Aqueous solutions of sodium bicarbonate (NaHCO 3 ) and sodium chloride (brine) were saturated.

67 [001001 Analytical thin layer chromatography (TLC) was carried out on Merck Kieselgel 60 F 2 54 plates with visualization by ultraviolet and/or anisaldehyde, potassium permanganate or phosphomolybdic acid dips. [01001 Reverse-phase HPLC chromatography was carried out on Gilson 215 liquid handler equipped with Waters SymmetryShieldTM RP18 7p.m (40 x 100mm) Prep-Pak cartridge. Mobile phase consisted of standard acetonitrile (ACN) and DI Water, each with 0.1% TFA added. Purification was carried out at a flow rate of 40mL/ min, and a gradient such that the peak of interest was eluted between 12-15 min in a 30 min run. [01011 NMR spectra: 1H Nuclear magnetic resonance spectra were recorded at 500 MHz. Data are presented as follows: chemical shift, multiplicity (s = singlet, d = doublet, t = triplet, q = quartet, qn = quintet, dd = doublet of doublets, m = multiplet, bs = broad singlet), coupling constant (J/Iz) and integration. Coupling constants were taken directly from the spectra and are uncorrected. [0102] Low resolution mass spectra: Electrospray (ES+) ionization was used. The protonated parent ion (M+H) or fragment of highest mass is quoted. Analytical gradient consisted of 10% ACN in water ramping up to 100% ACN over 5 minutes unless otherwise stated. 2.

3 , Xantphos, and Pd 2 (dba) 3 in dioxane was purged with argon for 5 min after which a condenser was added under argon flow. The reaction was heated to reflux (ca 110 "C) for 4-18h. The crude mixture was filtered and the solid filter cake was rinsed thoroughly with MeOH and DCM. The filtrate was concentrated in vacuo and purified by column chromatography. [0105] Whereever deprotection of aryl methoxy was necessary, the following general procedure was employed. To a solution of the aryl methoxy compound in DCM was added BBr 3 (either 1 M in DCM or neat). The reaction was checked for completion and additional BBr 3 was added if needed. The reaction was quenched with NaHCO 3 and basified to ca. pH 10-11. The biphasic mixture was filtered and the collected solid was rinsed with water. Trace solvents were removed in vacuo.

Kinases tested included the src family (primarily src and yes), some angiogenic growth factor receptors (Fgfrl, Vegfr, and Pdgfrp) and the ephrin, EphB4. All kinase reactions were conducted in 96-well plates with a final reaction volume of 50 ul. Src Family [04741 Recombinant human c-Src or Yes (28 ng/well, Panvera/Invitrogen, Madison WI), ATP (3 pM), a tyrosine kinase substrate (PTK2, 250 pM, Promega Corp., Madison WI), and test agents (at concentrations ranging from about 1 nM/I to about 100 pM/1), in the presence of Src kinase reaction buffer (Upstate USA, Lake Placid NY). After reacting for about 90 minutes at room temperature, residual ATP was determined using a luciferase-based assay (KinaseGlo, Promega Corp.) as a measure of kinase activity. Data 271 from four wells were then averaged and used to determine IC 50 values for the test compounds (Prism software package, GraphPad Software, San Diego CA). Growth Factor Receptors [04751 Pdgfrp (0.16ug/well, Panvera/Invitrogen) 500 nM ATP and the PTK2 peptide (700uM) were combined with compound and reaction buffer as noted above for src. The reaction was incubated for 60 minutes at 37C, and the residual ATP concentration was determined using the luciferase-based technique also noted above. [0476] FGFR1 and VEGFR2 kinase assays were similarly performed. FGFR1 (76ng/well, Panvera/Invitrogen) was combined with 12.5mg/ml poly(glu4tyr) (Sigma) and 2.5uM ATP. VEGFR2 (14. lU/well, Cell Signaling/ProQinase) was used with 0.3mg/ml poly(glu4tyr) and 1.5uM ATP. Both were incubated for 60 minutes at 37C, and the residual ATP was measured via luminescence, per the procedure described above. EphB4 [04771 EphB4 kinase activity was similarly measured, using the luciferase-based technique described above. 28.9mU/well EphB4 (Upstate) was reacted with 1mg/ml poly(glu4tyr), 6uM ATP and test reagents. The reaction was incubated for 60 minutes at 37C and the residual ATP concentration was measured. [04781 The test results for inhibition of Src kinase are presented in Table 1, and the test results for inhibition of some other kinases (i.e., Yes, EphB4, and Pdgfrs) are presented in Table 2. The abbreviation "IC 50 " means that a particular compound of the invention, when present at the specified concentration, inhibited the kinase by 50%.
